- Supports any language including syntax highlighting and pretty printing in HTML
- Compatible with Vim (literate.vim)
- Highly customizable (you can add your own HTML or CSS)
- Runs fast – wc.lit compiled for me in 7ms for both code and HTML output
- Supports TeX equations with
Inspired from CWEB:
- Automatically generates hyperlinks between code sections
- Formatted output similar to CWEB
I wrote lua4py page using Literate.
